Humans can't make insulation better than the one sheep grow. We've tried, but Merino wool outperforms synthetic materials for comfort, heat retention, moisture-wicking, and odor resistance. Instead of trying to one-up nature, we're working with it. Grown by sheep, perfected by technology, our Thermo Collection starts with the highest quality, hand-selected New Zealand wool. We send that wool to Germany where it gets blended with just enough synthetics to create the perfect stretch and woven into yarn. We use that yarn to make our durable, ultra-comfortable Thermo Collection.

Wearing cotton layers is kind of like fishing a Durham Ranger on your favorite trout river. Just because something's a classic, doesn't make it effective. Our Thermo Collection is built from the highest quality Merino wool to keep you warm on even the coldest days while naturally wicking moisture away from the body. Merino also naturally resists odor, so when you’re on day 4 of that week-long trip, your buddies won’t complain about the smell.

Quarter zip neckline with extended collar for warmth, heat regulation, and protection. Integrated thumb loops provide maximum skin coverage and hold sleeves in place when adding or removing layers. Articulation in armpits limits binding in underarms when layering.
